mschodnhrdundtolnthuomnPatentmdmnkingputdmnm To all whom it may concern:

Be it known that I, GRORGE HEM, of Naperville, in the county of Du Page, and State of Illinois, have invented a new and useful compound for building-purposes; and I do hereby declare the following to he a full, clear, and exact description of the same.

The nature of my invention consists in taking the ingredients hereafter specified, and simply mixing them together, and putting in water enough to make the mixture of the plastic state of ordinary mortar used by plasterers.

The mixture, or compound thus formed is then mouldeddn blocks, oif any suitable size or shape for hfiiyilesirerl purposes,'0u' it may be gpggmp a roof, to form an outside ccatfo'r it inay be plastered upon the outside of a house-wall which has been previously lathed, or put in any other place where it is desirable to have a hard, impervious coating. When the compound thus formed becomes dry, it becomes extremely hard, and is highly impervious to the action of the elements, which tend to destroy the ordinary prepared building-material.

To enable those skilled in the art to understand how to manufacture and use my invention, I will proceed to describe the same with particularity.

To one art of stone-lime and one part of waterliine ccen hen% I Ed irom iour to eight parts oi coal Ts'h' s an coa ust mixed in about equal quan 1 ice, and, to this mixture, I add about two pounds of tash to each bushel of cement used. I then add water dinary mortar used for plastering-purposes, stirring the same while the water is being added, in order that the difirfiFiiiQrdiEfitfiiffi be'well'mixed together.

The mixture is moulded or applied for use when it is in this plastic state, and left to dry.

The quantity of coal-ashes and coal-dust used, in proportion to the quantity of lime and cement, depends upon the quality of the lime.

Having thus described the nature and use of my invention,

What I claim, and desire to secure by Letters Patout, is-

A compound for building-purposes, manufactured substantiallyas herein described.

GEORGE HEIM.
